High‑Temperature Hotplate Stirrer

The DLAB LCD Digital 4‑Channel Hotplate Magnetic Stirrer is a modular, high‑throughput benchtop platform engineered for the true parallel processing of up to four independent heating and stirring reactions in clinical diagnostics, pharmaceutical quality control, analytical chemistry, food and feed analysis, environmental testing, and academic research laboratories.

Featuring four independent ceramic‑coated stainless steel work plates (Ø135 mm each), the LCD Digital 4‑Channel Hotplate Magnetic Stirrer provides each channel with its own PID temperature control (25–340 °C, 1 °C increments), stirring speed control (200–1500 rpm, ±20 rpm accuracy), and dedicated high‑resolution LCD display for independent real‑time monitoring of temperature and speed. The single‑position stirring capacity is 10 L of water (40 L total) per channel. The PT1000 external temperature sensor ports (±0.2 °C accuracy) enable precise closed‑loop control of the actual sample liquid temperature on each channel.

Key user‑focused features for high‑throughput applications include true independent control of start/stop, temperature, speed, and display for each channel (parallel experiment control); four independent maintenance‑free, spark‑free brushless DC motors for extended life and low‑noise operation; ceramic‑coated stainless steel work plates with fast heat transmission and strong chemical resistance; and space‑saving design (698 × 270 × 128 mm, 9.5 kg) with 4 channels integrated into a single instrument—dramatically reducing bench space compared to four separate single‑channel units.

Safety is exemplary with TÜV certification (CE, cTUVus, FCC), an independent residual heat warning indicator (“HOT” flashes on each respective channel display at >50 °C and continues even after the unit is turned off, including unplugged, until each plate is safe to touch), independent over‑temperature protection (420 °C hardware cutoff per channel), and IP21‑rated dust/water ingress protection with an aluminum alloy housing for chemical resistance and excellent heat dissipation.

For the clinical laboratory scientist, trace element analyst, pharmaceutical QC chemist, food and feed analyst, and research scientist, the LCD Digital 4‑Channel Hotplate Magnetic Stirrer delivers the modular versatility, independent 4‑channel processing capacity, high‑temperature performance (up to 340 °C), and high safety required for parallel‑batch sample digestion for trace element analysis (blood lead, urine cadmium, heavy metals), multi‑condition dissolution testing, Kjeldahl nitrogen determination, Soxhlet extraction workflows, and multi‑parameter optimisation. For the patient, the reliable and reproducible performance of this high‑throughput instrument ensures that diagnostic tests and pharmaceutical products are accurate and efficient, directly supporting effective clinical decision‑making, appropriate treatment selection, and patient safety.
